Pipe and Flange Dimensions | Control Specialties

Hey Ed. Good video and information. Thanks for putting this together. One thing I'd like to point out is the ANSI class doesn't equal the psi capabilities it can handle. ANSI 150# flanges aren't rated for exactly 150psig as an example. They have a pressure and temperature chart to follow. Here's the engineeringtoolbox.com link showing this chart. www.engineeringtoolbox.com/ansi-flanges-pressure-temperature-d_342.html At 100°F or cooler ANSI 150# flanges are rated for 287psig. Once they get up to around 570°F is when they de-rate to 150psig. Basically, the hotter the pipe/flange gets the less pressure it can withstand. Hope this helps! Keep up the good work. Nick
